New Guinea Impatiens plant named ‘Applause Light Lavender’

ABSTRACT

A new and distinct cultivar of New Guinea Impatiens plant named ‘Applause Light Lavender’, characterized by its compact and mounded plant habit; freely branching growth habit; dark green leaves; freely flowering habit with flowers positioned above or beyond the foliage; large, light purple-colored flowers with white-colored centers; and tolerance to full sun conditions and low and high temperatures.

Botanical classification/cultivar designation: Impatiens hawkeri cultivar Applause Light Lavender.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri, and hereinafter referred to by the cultivar name ‘Applause Light Lavender’.

The new Impatiens is a product of a planned breeding program Inventor in Ashtabula, Ohio and Lompoc, Calif. The objective of the breeding program is to develop new freely flowering Impatiens cultivars with compact plant habit and interesting flower and foliage colors.

The new Impatiens originated from a cross-pollination made by the Inventor during the winter of 1997 of a proprietary Impatiens hawkeri seedling selection designated as code number 97-439-1, not patented, as the female, or seed parent, with a proprietary Impatiens hawkeri seedling selection designated as code number 96-633-3, not patented, as the male, or pollen parent. The cultivar Applause Light Lavender was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in controlled environment in Ashtabula, Ohio.

Asexual reproduction of the new cultivar by terminal cuttings taken at Lompoc, Calif., since November, 1998, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations. Plants of the new Impatiens differ from the parent selections primarily in flower and leaf color.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Applause Light Lavender’. These characteristics in combination distinguish ‘Applause Light Lavender’ as a new and distinct Impatiens cultivar:

1. Compact and mounded plant habit.

2. Freely branching growth habit, dense and full plants.

3. Dark green leaves.

4. Freely flowering habit with flowers positioned above or beyond the foliage.

5. Large, light purple-colored flowers with white-colored centers.

6. Tolerant to full sun conditions and low and high temperatures.

Plants of the new Impatiens can be compared to plants of the cultivar Applause Lavender, disclosed in U.S. Plant Pat. No. 12,650. In side-by-side comparisons conducted in Lompoc, Calif., plants of the new Impatiens differed from plants of the cultivar Applause Lavender, in the following characteristics:

1. Upper and lower leaf surfaces of the new Impatiens were green in color whereas upper and lower leaf surfaces of the cultivar Applause Lavender were green tinged with purple.

2. Plant of the new Impatiens had narrower leaves than plants of the cultivar Applause Lavender.

3. Plants of the new Impatiens had larger flowers than plants of the cultivar Applause Lavender.

4. Flower color of plants of the new Impatiens was lighter purple than flower color plants of the cultivar Applause Lavender.

5. Peduncles of plants of the new Impatiens were darker green in color than peduncles of plants of the cultivar Applause Lavender.

Plants of the new Impatiens can also be compared to plants of the cultivar Kicarl, disclosed in U.S. Plant Pat. No. 11,370. In side-by-side comparisons conducted in Lompoc, Calif., plants of the new Impatiens differed from plants of the cultivar Kicarl, in the following characteristics:

1. Plants of the new Impatiens were shorter, more compact and more mounded (not as upright) in plant habit than plants of the cultivar Kicarl.

2. Upper and lower leaf surfaces of the new Impatiens were green in color whereas upper and lower leaf surfaces of the cultivar Kicarl were green tinged with purple.

3. Plants of the new Impatiens had larger flowers than plants of the cultivar Kicarl.

4. Flower color of plants of the new Impatiens was lighter purple than flower color of plants of the cultivar Kicarl.

5. Peduncles of plants of the new Impatiens were dark green in color whereas peduncles of plants of the cultivar Kicarl were purple in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Impatiens.

The photograph comprises a side perspective view of a typical flowering plant of ‘Applause Light Lavender’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The cultivar Applause Light Lavender has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs and following detailed botanical description describe plants grown in Lompoc, Calif., during the winter, under commercial practice in a fiberglass-covered greenhouse. Plants used in the following description were grown in 15-cm containers for about seven to nine weeks after planting rooted cuttings. During the production period, day temperatures were about 21 to 24° C., night temperatures were about 16 to 18° C., and light levels were about 3,000 to 4,000 foot-candles.

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
